ARNAL, BOTI-I 0F MINNEAPOLIS, MINNESOTA BEAM CONNECTION This inventionrelates to a beam connection for use in building structures such assteel buildings, and the same is applicable wherever a load carryingbeam is connected to a vertical support or column. -In all bea is andgirders under load there exists a bending moment or couple which resiststhe external forces causing bending in the beam or girder. It isdesirable to develop a couple in the connections of a beam or` girderwhich Will be of equal magnitude with the couple in the beam, or aslarge as the bending moment requires. As the value Aof the couple in abeam connection depends upon the rivets, bolts or fastening meansconnecting it to its support or column, 1t is necessary that theserivets have a value that will develop a resisting moment equal to thebending moment in the beam.

It is an object of this invention, therefore, to provide a beamconnection comprising a bea-1n formed as an I-beam, connected to itscolumn or support by members including a pair of angle members securedt-o the top flange and web of said l-beam adjacent its connected end.,whereby the necessary resisting moment may be obtained.

It is a further object of the invention to provide a beam connectioncomprisingV a beam having the form of an I-beam, members connected tothe web of said beam for connecting the same to its support or column,rivets or bolts extending throughsaid members and said web together withangle members secured beneath and to thetop flange of said beam and tosaid members, and the web of said beam by some of the rivets or boltsconnectingsaid members to said web.

It is another object of the invention to provide a beam connectioncomprising a beam in the form of an I-beam, adapted to be connected atone end to a column and for this purpose having a pair of verticalangles secured thereto with one side respectively connected to the webof said beam and a pair of angle members disposed at each side of saidbeamand secured to the upperi'lange thereof by rivets or bolts, saidangle members having their other sides parallel to the web of said beamand engaging'said lirst Application filed October 19, `1927.

It is still another object of the invention to construct a beamconnection such as set forth in the preceding paragraph, an angle memberalso being provided extendingY transversely of said -beam above lthe topflange thereof and having a vertical flange projecting above said flangeadapted to be connected to the column or support of the beam, said anglemember being connected't-o aid top flange by some of the rivetsconneet-ing said second mentioned angle members to sai-d beam. y

Referring to the drawings, a beam co-nnection such as used in a steelbuilding is shown, comprising an I-beam 10. Vilhile this beam may be ofany desired construction and may be built up ot plates or angles, in theembodiment ot the invention illustrated it is shown as a rolled beam andthe same is shown particularly in the form ot a comparatively recentCarnegie beam section made and marketed by the Carnegie Steel Company,as illustrated and described in their hand book entitled Carnegie BeamSections, 1st edition, published January 1, 1927. In this type otsection the web or" the beam makes a sharp inside right angle with theflanges ot the beam which is ot' uniform thickness. In order to tastenthe beam to its support, angles 11 are provided, one oi the sides oiwhich is respectively riveted to the side ot a plate 12 which isdisposed below the beam 1 0, havingl its top edge disposed closelyadjacent the bottom ot said beam, said plate as shown being triangularin shape. rllhe other sides of the angles 11 project outwardly .tromplate 12 and these sides are provided with holes 11a adapted to receiverivets or bolts securing the same to a column. The plate 12 is connectedto the angles '1 by the rivets 13. The beam 10 has its lower flange 10acut away adjacent its end and the angles 11 extend along the web of saidbeam parallel thereto, to a point adjacent the top iiange 10b ot thebeam. Plates 14 are disposed between the web ot beam 10 and the sides otthe angles 11. The plates 14 entend from the bottom ot the beam 10 toadjacent the top flange 10b there of., T he plates 14, angles 11 and theweb of said beam are connected by the rivets 15. Another pair of anglemembers 16 is provided, which members may be formed by cutting astandard channel, bending a plate, or may be out from standard anglemembers. Said angle members 16 have one ot their flanges 16a inengagement with the under side ot flange 10?) of beam 10 and connectedto said -tlange by the rivets 17. The ilanges 16 have their other sides165 extending parallel4 to web 10 and in engagement with the outer sidesorn the angles 11 and rivets 18 connect the members 11 and 16, plates 14and the web of beam 10. The members 16 extend inwardly quite a distancealong the top web 10b from the angles 11 and said members are shown ashaving an inclined edge so that their inner portion is triangular. Thesides of the members 16 parallel to the web ot beam 10 are spacedtheretrom as shown in Figs. 4 and 5, and spacing thimbles 19 aredisposed between said sides and web of beam 10, rivets 20 eXtendin gthrough members 16, thimbles 19 and the web of beam 10 and securing thesame together. Another angle member 21 is disposed on top of flange 10band extends transversely thereof, said angle having its side in contactwith said dange connected thereto and to the side oi the member 16 bythe rivets 22. The angle 21 has a vertical tiange projecting upwardlytrom flange 10b, the outer surface of which is shown as substantiallyiiush with the outwardly extending sides of the angles 11, and providedwith holes 21o adapted to receive rivets or bolts to secure said anglesto a col umn. jingle members 23 are provided, having their sidesengaging the sides of plate 12 and secured thereto by the rivets 24 andhaving their other sides engaging the bottom et ilange 10a and securedthereto by the rivets A pair ot angle members 26 are also provided,disposed along the inclined edge of the plate 12 and have one of theirsides disposed against said plate and connected thereto by the rivets 2,the other sides ot said angles projecting outwardly from plate 12.

In the described structure it will be seen that tho desired value of thebending moment resisting the load on beam 1() will be determined by therivets or bolts in the holes 11a which secure the beam to the column.rlhe plate 12 is made of the proper thickness to give the necessarydouble shear value to the rivets 13. For the upper arm of the re`sisting couple, the rivets 15 connect angles 11 to the web ot beam 10,which web is coinparatively tiin. These rivets also pass through the twoplates 14. The combination ot the plates 14 and said thin web reducesthe value of the rivets 15 so that it is not possible to develop theproper moment without additional rivets. ln the present invenn tion thisis accomplished by the provision of the angle members 16. rlhe rivets 1Sare given a value ot double shear by the angle members 16 an additionalreduced bearing value on the web of beam 10. The rivets 25 develop ahorivontal shear at their location in the connection and this shear istransferred to the plate 12 by the angles 23. From the above descriptionit is seen that applicant has provided a very effective beam connectionand one that easily made from standard structural parts. llhe principalteatue of the invention is the angle members 16. These angles, inconnection with the rivets 17 and 18, serve to develop the requiredresisting moment in the connec tion. The angle 21 in connection with theangle 16 together with its rivets 22 materially increase the value otthe resisting moment in the connection, and adds to the lateralstitlness and rigidity of the connection. The members 16 and 21 withtheir connectin rivets, together with the rivets 15 and the parts belowthe same, are specially useful in developing the reverse bending momentswhich occur in wind bracing beams and girdw lll) ers of buildings. Asabove stated, the invention is particularly applicable to the Carnegiebeam section mentioned, for the reason that the angle members 16 can beplaced fiat against the under surface of the flange which extends in aplane at right angles to the web. The angle member 16, of course, couldbe applied to any type of I-beam secn tion, but in the standard sectionswould have to be formed somewhat to engage with the sloped surface ofthe flanges. ily be seen that the angle member 16 can be made by cuttingin two a standard channel, thus obtaining two of the angle meinbers.Vrlhe angle members 16 will usually be made of standard angles or cutmembers as stated, but may, of course, be made from plates bentspeciallyfor the purpose, if desired.. The effectiveness of thestructure has been amply demonstrated and the same is being installed inactual buildings.
